Operation Parameters by Reference

You can select to highlight parameters declared as 'Kind: inout' or 'Kind: out' with an additional user-defined prefix or suffix.

If you select the Highlight References checkbox, you can also indicate whether a prefix or suffix should be used, and the actual reference character to use. In the example image, the & character has been set as a prefix.

When you declare a parameter of type inout, it is assumed you are passing the parameter by reference rather than by value. If you have elected to highlight references, then this is displayed in the Diagram View.

The example to the left shows that, in the getName operation, the parameter strName is a string reference, and is highlighted using the chosen character and position.
